Some disclosed methods involve controlling a fingerprint sensor system to scan a portion of a user's digit and obtaining fingerprint image data corresponding to the portion of the user's digit. Some such methods involve obtaining defect data identifying one or more defective areas corresponding to an active fingerprint sensor area and determining whether the defect data indicates one or more defective areas corresponding to a touched portion of the active fingerprint sensor area from which the fingerprint image data were obtained. Some such methods involve determining, responsive to determining that the defect data indicates one or more defective areas corresponding to the touched portion, whether fingerprint image data corresponding to the one or more defective areas can be rectified and, responsive to determining that the fingerprint image data can be rectified, rectifying the fingerprint image data corresponding to the one or more defective areas.

Dynamic rectification of fingerprint image portions corresponding to defects

Apparatuses, systems, and methods are provided for use with expandable displays. In some implementations management techniques and/or systems are provided that allow for access to expandable display functionality to be managed to as to potentially prolong device battery life. In other or additional implementations, techniques and/or systems are provided for potentially safeguarding devices with expandable displays from damage in the event of a fall or drop event. In yet other or additional implementations, techniques and/or systems are provided for determining the expansion state of an expandable display, thereby allowing corrective measures to be taken if the actual expansion state of the expandable display does not align with the expected expansion state of the expandable display.

Some disclosed methods involve controlling a fingerprint sensor system to scan a portion of a user's digit on a surface of an apparatus using a plurality of trial fingerprint sensor system parameters and selecting, from among the trial fingerprint sensor system parameters, one or more personalized fingerprint sensor system parameters for inclusion in a set of personalized fingerprint sensor system parameters. Some disclosed methods involve selecting, based on the one or more personalized fingerprint sensor system parameters, an existing fingerprint sensor system parameter data structure that includes a set of existing fingerprint sensor system parameters, obtaining additional fingerprint sensor system parameters from the set of existing fingerprint sensor system parameters for inclusion in the set of personalized fingerprint sensor system parameters, and storing the set of personalized fingerprint sensor system parameters for future scans of the fingerprint sensor system.

Personalized fingerprint sensor system parameters

In some implementations a method may involve presenting a graphical user interface in a first configuration on a display of an apparatus. The first configuration may correspond with a first display area. The method may involve enabling operation of a fingerprint sensor system in a first fingerprint sensor area corresponding with at least a portion of the first display area. The method may involve presenting the graphical user interface in a second configuration on the display and enabling fingerprint sensor system operation only in a second fingerprint sensor area corresponding with the second configuration.

Adaptive activation of fingerprint sensor areas

Methods, devices and systems for controlling a fingerprint sensor system are disclosed. Some examples involve receiving a contact indication corresponding to a contact of an object with a surface of an apparatus and determining, responsive to the contact indication, multiple force values corresponding to contact of the object with the surface during a force monitoring time interval. Some examples involve determining whether at least a plurality of the multiple force values exceeds a force threshold and controlling a fingerprint sensor system based, at least in part, on whether at least the plurality of the multiple force values exceeds the force threshold.

Force-based finger detection for fingerprint sensor systems

Some disclosed methods involve controlling, via a control system of an apparatus, a touch sensor system to obtain touch sensor data in a touch sensor system active area of the apparatus. Some disclosed methods involve controlling, via the control system, a fingerprint sensor system of the apparatus to obtain fingerprint sensor data in a fingerprint sensor system active area of the apparatus. Some disclosed methods involve determining, via the control system and based on the touch sensor data, n touch locations corresponding to n last user touches and controlling, via the control system, a size of the touch sensor system active area based, at least in part, on the n touch locations.
